He told officers that he was hurt, upset and drunk when he sent the messages and admitted that the victim had broken up with him, but that he still considered her as his girlfriend.

Detective Constable Heidi Adams, the investigating officer from Harrow's Community Safety Unit, said his behaviour left the victim “fearing for her life”.

She said: “Thomas refused to accept that his relationship with the victim was over and so he subjected her to weeks of harassment which culminated in him calling her dozens of times over a few hours and leaving her increasingly angry messages where he repeatedly threatened to kill her or cause her serious harm."
